True or false? Water will not last us long. Why so?
True. The ramifications of water shortages are staggering, less water for crops, less drinking water, less water to clean and now you have the spread of disease being tied to uncleanly conditions. The third world nations will be hit the hardest and the world leaders will ration water per individual or household. You will also see nations fighting over fresh water and the technology industry trying to find new and more efficient ways to desalinate sea water. -Yahoo!answers
True. Fresh water is a renewable resource, yet the world's supply of clean, fresh water is steadily decreasing. Water demand already exceeds supply in many parts of the world and as the world population continues to rise, so too does the water demand. Awareness of the global importance of preserving water for ecosystem services has only recently emerged as, during the 20th century, more than half the world’s wetlands have been lost along with their valuable environmental services. Biodiversity-rich freshwater ecosystems are currently declining faster than marine or land ecosystems. The framework for allocating water resources to water users (where such a framework exists) is known as water rights. -Wikipedia
False. Water crisis is a term that has been used by some to refer to the world’s water resources relative to human demand. The term has been applied to the worldwide water situation by the United Nations and other world organizations.Others, for example the Food and Agriculture Organization, claim there is no water crisis.The major aspects of the water crisis are allegedly overall scarcity of usable water and water pollution. 2 billion people have gained access to a safe water source since 1990. The proportion of people in developing countries with access to safe water is calculated to have improved from 30 percent in 1970 to 71 percent in 1990, 79 percent in 2000 and 84 percent in 2004, parallel with rising population. This trend is projected to continue. The Earth has a finite supply of fresh water, stored in aquifers, surface waters and the atmosphere. Sometimes oceans are mistaken for available water, but the amount of energy needed to convert saline water to potable water is prohibitive today, explaining why only a very small fraction of the world's water supply derives from desalination- Wikipedia

By 2050, an extra 1.5 billion people will live in Asia, piling even more pressure on already scarce food supplies, said a study by the UN's Food and Agriculture Organization (FAO) and the International Water Management Institute (IWMI). It also forecast that by 2050, developing countries in Asia look likely to need to import more than a quarter of the rice, wheat and maize needed to feed their populations.-Agrifeeds
In India, home to 1.002 billion people, key aquifers are being overpumped, and the soil is growing saltier through contamination with irrigation water. Irrigation was a key to increasing food production in India during the green revolution, and as the population surges toward a projected 1.363 billion in 2025, its crops will continue to depend on clean water and clean soil
. Egypt, whose population of 68 million may reach 97 million by 2025, gets essentially no rainfall. All agriculture is irrigated by seasonal floods from the Nile River, and from water stored behind the Aswan High Dam. Any interference with water flow by Sudan or Ethiopia could starve Egypt. - Whyfiles

Nearly 1 billion of the world's people do not have an "adequate" supply of water, and roughly 2 billion do not have access to "adequate" sanitation facilities (with "adequate" defined as a single water tap shared among hundreds of people). Most of these people are in the world's developing nations. -waterencyclopedia
What are some of the problems that occur with water shortage?
As we in water-rich countries take our shower, water the lawn or laze about in the pool, it' easy to forget that fresh water is a life-or-death issue in many parts of the world. Of a population of roughly 6.1 billion, more than 1 billion lack access to potable water. The World Health Organization says that at any time, up to half of humanity has one of the six main diseases -- diarrhea, schistosomiasis, or trachoma, or infestation with ascaris, guinea worm, or hookworm -- associated with poor drinking water and inadequate sanitation. About 5 million people die each year from poor drinking water, poor sanitation, or a dirty home environment -- often resulting from water shortage . -Whyfiles

Evaluation Question: So What?
Is there a better solution to warn others about water shortage, other than making a poster? What is it?
Video Youtube, Power Point
Extra Questions:
What is the main cause of our water shortage?
There are simply too many causes of water shortage as water is used for many things. But some causes are poor management of irrigation leading to salinization of large amounts of water supply.
Salinization means: In a soil of an arid, poorly drained region, the accumulation of soluble salts by the evaporation of the waters that bore them to the soil zone.
What can we do to prevent water shortage?
Preventing water shortage is the only way to keep water on Earth! Water is used for many things and we should try and use a very little amount of it.
